(Cl. 1li-164) l 4 Claims.

My invention relates to swinging doors and the like, and has among itsobjects and advantages the provision of an improved hinge particularlywell suited to an all-metal door and frame construction.

In the accompanying drawings:

Figure 1 is a face View of a door and a door frame showing my inventionapplied thereto;

Figure 2 is a perspective view of one of the hinges;

Figure 3 is an enlarged sectional view taken along the line 3-3 ofFigure l;

Figure 4 is a view similar to Figure 3 but il lustrating the door in anopen position; and

Figure 5 is a view similar to Figure 3 but i1- lustrating a modifiedform of hinge structure.

In the embodiment selected for illustration, the door I0 is connectedwith a frame I2 through the medium of hinges I4. In Figure 3, the doorI0 includes an inner metallic wall I6 and anouter metallic wall I8spaced therefrom. An angle 20 is Welded to the walls I6 and I8 foriixedly relating the same.

Frame I2 includes an angle 22 to the wing 24 of which is secured ametallic trim 26, as-by weld- I8 and the trim 26 have curvedand adjacentedge margins 28 constituting hinge stops for limiting further pivotalmovement of the door when moved one hundred and eighty degrees from itsfully closed position.

To the wall I8 is Xedly secured a hinge wing 30 having loops 32 aligningwith loops 34 on a hinge part 36 of U.shaped contour when viewedaccording to Figure 3. A hinge pin 38 is inserted through the alignedloops 32 and 34 for pivotally connecting the wing 30 with the wing 40 ofthe hinge member 36. The second wing 42 of the hinge member' 36 isprovided with loops 44 aligning with loops 46 on a right angular flange48 of a hinge Wing 50. A hinge pin 52 is inserted in the alignedloops 44and 46. The wing 30 may be welded to the Wall I8 while the wing 50 issecured to the trim 22 by screws 53.

To the hinge member 36 is welded a hinge control 54 having a rightangular ilange 56 attached to the Wing 42 and a flangek 58 fittingagainst the bight of the hinge member 36 vand curved at 68 to haveedgeengagement with the Wing 30 in the closed position of the door I0.Both hinge members 36 of the hinges I4 are fixedly secured to the hingecontrol 60, the latter extending A throughout the full height of thedoor.

In operation, the door I0 lies flush with the face of the frame I2 inthe closed position of .the door, Notwithstanding this arrangement the`spending to the wings ying side members and door I0 may be swung onehundred and eighty degrees about the axes of the pins 38 and 52 to itsfully opened position of Figure 4.

The hinge control 54 fixedly connects the hinge members 36 of the twohinges I4 so that the hinge members operate-in unison. With the door I0swung to its fully opened position of Figure 4, one curved end 28 hasengagement with the wing 40 of the hinge member 36 and the other end 28has engagement with the wing 42, so that the door is limited fromfurther pivotal movement in its opening direction.

Figure 5 illustrates a modification in that a U member 82 is secured tohinge wings 64 corre- 40 and 42 of Figure 3. The U member 62 is weldedto the hinge control 66, and the remaining structure is identical withthat illustrated in Figures 2, 3 and 4.

Without further elaboration, the foregoing will so fully illustrate myinvention, that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.

Iclaim: i

1. `Means for mou ting a door on its frame, comprising lower and upperhinges, each including side members and an intermediate member pivotallyconnected by aligned hinge pin engag-` ing loops, the side members beingadapted to be connected to the door and frame and the intermediatemember being of U-form in crosssection and adapted to be recessed in thedoor and frame, curved stop members xedly related to the door and framepartially embracing the loops to limit the opening movement of the door,and a stop carried by the intermediate members of the hinges and adaptedto cooperate with those side members of the rhinges secured to the doorto limitl the closing movement of the door.

2. A hinge of the character set forth comprisan intermediate member, theintermediate member being of U-form in cross section, and a stop carriedby the intermediate member and adapted to cooperate with said sidemembers to limit the movement of said side members in one direction withrespect to the other member of the hinge said stop comprising achanneled bar of angular formation at one side and curved at theopposite side fixed to the intermediate member and engageable with saidside members to limit the closing movement of the door.

termediate said side members, interfltting aligned loops formed on thefree longitudinal edges of `the U-shaped member and said side members,

hinge pins extended through said loops, curved stop elements nxedlyrelated to the door and frame ,respectively and partially embracing eachaligned loop assembly so as to limit the opening movement of theU-shaped member relative to the frame and the door with relation to theU- shaped member, andmeans for limiting. the clos- 10 ing movement ofthe door.
